MACHINE FOR SEPARATING IUTE, RANIIE, &C., FROM THE STALK.

SPECIFICATION forming part of Letters Patent No. 358,827, dated March 8, 1887.

Application tiled March 1Q, 1856. Serial No.194,960. (No model.)

T0 all whom, 'it may concern:

Be it known that I, ALBERT ANGAELL, of East Orange, in the county of Essex and State of New Jersey, have invented an Improvement in Machines for Separating Jute, 85e., from the Stalk, of which the following is a specification.

In this improvement I make use of elastic feeding-rollers, which serve to pass the stalks of jute, ramie, or similar material along through the machine, and also to hold the stalks and liber from being drawn through too rapidly by the cleaning portion of the mechanism, and I split `the stalks longitudinally by a stationary knife, and loosen the bark andl crack the woody liber by pricker-rollers having longitudinal ribs or blades acting at oppo site sides of the splitting-knife, and the fiber is then subjected to the action of beaters and brushes, to remove the bark and woody portions and leave the fiber in a condition for market.

In the drawing I have represented my improvement by a section longitudinally ot' the machine and transversely of the respective rollers.

The stalks of jute, ramie, or other fiber are to be laid upon the table or feedboard H, and they are passed in, butt-end first, between a pair of elastic feed-rollers, A A, and by them pressed against and split upon the stationary knife E, so that the woody interior of the plant is divided longitudinallyto give greater facility for thc removal of the woody portion. At each side of th'is knife E are the` rollers B, the surfaces ot' which are channeled longitudinally, leaving thin blades or pickers upon the surfaces of such rollers, for the twofold purpose of loosening and partially detaching the bark and for partially crushing and breaking the woody stock.

The beaters C O are composed of radial blades projecting from central shafts that are geared together and revolve in the direction indicated by the arrows, and the edges of these blades pass by each other, so that the stock and fibrous materials between the beaters are bent alternately in opposite directions, and the back edge ofthe knife E is also rounded,so that the beaters act against the fiber and stalks at these places to break up the woody portions thereof as the stalks pass along over the back edge of such knife; and D D are cylinders around which pass endless belts of brushes G, the fiber being fed along through between these brushes, and the bark or other foreign matter 'is brushed off the fiber by such endless belts of brushes, and the fiber as delivered from these brushes is in a condition ready for market.

It will now be apparent that the beaters O perform two distinct operations. First, the woody portions of the plant are broken transversely hy being bent in alternate opposite directions, and, second, the fiber is rubbed and stripped longitudinally to remove the bark and foreign matter, in consequence of the beaters traveling at a greater speed than the fiber as it is supplied by the feedrollers; hence the fiber reaches the brushes G in nearly straight and comparatively clean condition, and these brushes complete the cleaning of the ber, so that it is delivered in a condition adaptedto market.

The means made -use of for revolving the respective parts may be of any desired character. It is preferable to gear the respective pairs of rollers together, and to drive the rollers B and A at the same surface-speed, or nearly so. ten times as fast as the feed-rollers, and the brushes should travel about twice as fast as thc'feed-rollers.

I claim as my inventionl. The combination, with the feed-rollers A and splitting knife E, of the rollers B B, having ronghened surfaces to act upon the liber at each side of the knife E, the beaters O, formed of longitudinal blades interlocking, as specified, and acting upon theber as it passes away from the knife E, and the endless belts of brushes, substantially as set forth.

2. The combination, with the feedrollers A and the knife E,for splitting the stalks, of the rollers B at the sides of the knife E and aeting upon the split stalks to loosen the woody matter and bark from the fiber, substantially as set forth.

Signed by me this 26th day of February, A'. D. 1886.
